Wacker Neuson 5000186621 Nut Flange 1/2-20 Hex Grade 8

The Wacker Neuson Nut Flange 1/2-20 Hex Grade 8 is a genuine OEM fastener designed for CRT60-66K and CRT60-74L series reversible plate compactors. Sourced directly from Wacker Neuson, this replacement meets the exact torque and dimensional specifications required for correct assembly. Confirm your model number before ordering — this part fits multiple CRT60 configurations, including the CRT60-66K and CRT60-74LX.

Key Features

• Grade 8 Tensile Strength — High-strength Grade 8 rating delivers the clamping force and fatigue resistance demanded in heavy-duty compaction applications.
• Integrated Flange Bearing Surface — The built-in flange distributes load evenly across the mating surface, eliminating the need for a separate washer and ensuring consistent seating at installation.
• Genuine OEM Part — Manufactured by Wacker Neuson to the same specification as the original hardware, so thread engagement and torque values match what the machine was designed around.
• Broad CRT60 Series Coverage — Fits CRT60-66K and CRT60-74L series plate compactors, covering multiple model variants within the CRT60 lineup.
• Correct Hardware for Critical Joints — Using the correct grade and thread specification prevents fastener failure at joints that are subject to vibration, which can lead to component loosening or structural damage over time.

A flange hex nut is a standard hex nut with a wide, integrated flange on one end that acts as a built-in washer. This flange spreads the clamping load over a larger surface area, helping to prevent the nut from pulling through or damaging softer mating components. On high-vibration equipment like plate compactors, using the correct grade of fastener is critical — an underspecified nut can stretch, loosen, or shear under load, leading to component misalignment or failure. Replacing worn or damaged hardware with the correct OEM specification part restores joint integrity and keeps assemblies torqued to spec.
